Catalyst Game Labs have released Technical Readout: 3085 in PDF format as well as Record Sheets: 3085.
From their website:
We wanted to wait until Gen Con…but we just couldn’t. We’re so excited for the BattleTech community to dive into this book we just couldn’t wait any longer…not to mention giving those not attending Gen Con a boost in the arm.
In December 3076, Devlin Stone marshalled the nations of the Inner Sphere and began Operation SCOUR. The two-year final push to Terra was the bloodiest fighting seen in centuries. In the end, Terra had been freed with the Word of Blake scattered to the darkest corners of the universe. Stepping into that vacuum, Stone forged a new “Terran Hegemony” in The Republic of the Sphere. With the end of the Jihad, the survivors are rebuilding their shattered armies, introducing new machines to replace those whose factories ceased to exist in the fires of the Jihad.
BattleTech Technical Readout: 3085 gives a detailed look at the machines introduced during the waning days of the Jihad and into the founding days of Devlin Stone’s Republic of the Sphere.
